The best bet would be to get as close to his bedroom as possible,but i would prefer to do this later in the season as i dont want to scare all the deer away if they detect me.Earlier in the season i would prefer to go deep in the bush and find the thickest nastiest stuff i can find,usually there would be enough shooting lanes,or trim some before season starts,and hunt.The buck would make a mistake sooner or later.The only time you would see a mature nocturnal buck in the clear would be during the rut chasing does or in a feed field in the middle of the night
